Beschreibung
Zusammenfassung:	Disclosed is an insulation resistance maintenance system for a fuel cell, comprising: a fuel cell stack; a refrigerant line allowing a refrigerant to flow through the fuel cell stack therein; a circulation pump formed on a refrigerant line and circulating the refrigerant inside the refrigerant line; an ion eliminator formed on the refrigerant line to remove impurities or ions contained in the refrigerant inside the refrigerant line; and a controller measuring insulation resistance of a high voltage terminal connected to the fuel cell stack, determining whether the recovery control is necessary based on the measured insulation resistance, and, if recovery control is required, controlling the circulation pump to vary the flow of refrigerant through the ion eliminator. 연료전지 스택; 내부에 냉매가 연료전지 스택을 통과하여 유동되도록 형성된 냉매 라인; 냉매 라인에 형성되어 냉매 라인 내부의 냉매를 순환시키는 순환펌프; 냉매 라인에 형성되어 냉매 라인 내부의 냉매에 포함된 불순물 또는 이온을 제거하는 이온제거기; 및 연료전지 스택에 연결된 고전압단의 절연저항을 측정하고, 측정한 절연저항을 기반으로 회복제어가 필요한지 여부를 판단하며, 회복제어가 필요한 경우 이온제거기를 통과하는 냉매의 유동을 가변하도록 순환펌프를 제어하는 제어기;를 포함하는 연료전지의 절연저항 유지시스템이 소개된다.
